The Mortality rates are the number of deaths per 100 surgeries. Example: On average, 1.95 out of 100 patients who had CABG surgery died while in the hospital or within 30 days after being discharged from the hospital.
Lower mortality rate is better and means fewer deaths.
Data is from 2010.

* Operative Mortality includes: (1) all deaths occurring during the hospitalization in which the operation was performed, even after 30 days; and (2) those deaths occurring after discharge from the hospital, but within 30 days of the procedures.
